Are there some templates or examples I can find? I haven't played
much with CoPP and don't hear a lot of accolades for doing this. The
other obvious question would be "does this run in hardware or in
software?". Hmm, doubt if the packet ASICs are processing ACL's.
Provided QoS is globally enabled with "mls qos", CoPP is done in
hardware[1] on 6500/sup720, by adding QoS policy-maps into the PFC/DFC
qos path.
You're sure you need mls qos for that? I was under the impression that
CoPP is always done in hardware (as long as the specific rules permit).
That is my understanding:
"""CoPP is not be enabled in hardware unless you have enabled PFC QoS
globally with the mls qos command. If you do not enter the mls qos
command, CoPP is not hardware-accelerated."""
